Windows 10: Why when I try to change my password it says unavailable?

It shows me it's unavailable and the learn more button doesn't help

Pin unavailable and password changed

I have just had a problem after trying to login to Windows, I usually get asked to enter a pin number but this time it gives an error sayimg pin is unavailable then changes to a password. I have never set a password but on entering my Microsoft account password which I assumed would work but it says it is wrong. I have tried all alternative passwords including previous Microsoft passwords and none worked, I also noticed the no network symbol was in the bottom right hand corner.

When I attempt to use the "Forgot password" button I get a screen saying "Wait a moment" for 45 - 60 seconds before reverting to the password screen.

The only major change I made was attempting to remove Avast (I installed Kaspersky yesterday), no other major changes have been made.

I don't have a password reset disc as none came with the computer.

How do I log back in?

 

Pin unavailable and password changed

It's not possible to set a PIN for any account without first setting a password for that account.

 

Trouble Changing Wi-Fi Password


I've been following the following steps to change my Wi-Fi password for some time:

1. Launch Control Panel.
2. Click "Network and Internet."
3. Click "Network and Sharing Center."
4. Click "Wi-Fi...."
5. Click "Wireless Properties."
6. Click the Security tab.
7. Check "Show characters."
8. Enter the password in "Network security key."

Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?
